But Roy changed the tempo of the game in the second set and forced Cheema on the defensive, eventually breaking him in the fifth and seventh games to take the set 6-2. He then kept up the pressure and took the final set quite easily at 6-1.

Second seeded Gupta was in excellent form and eliminated eighth seed Mutib Pasha in straight sets 6-0, 6-1 without encountering any resistance.

Third seeded Khan was also in fine touch and outplayed sixth seeded Sandeep Kumar of India in straight sets 6-1, 6-1.

Shokeen then caused the upset of the tournament, eliminating fourth seeded Sivendaran Nishendaran of Sri Lanka in a closely contested match. Shokeen prevailed 7-6, 6-4, taking the first set tie-break at 7-4.

Top-seeded Punjaporn outplayed Puja in straight sets 6-0, 6-1 with several down-the-line and crosscourt winners to which the Indian had no answer.

In the second semifinal, Nungnudda beat second seeded Shweta 6-4, 6-4 in a well-contested match that saw several long rallies.
